# Fillers Method This method is on par with the No-Sand Method in terms of quality of finish but is a slightly slower process. However, it is faster than hand-sanding or using a Dremel to post process your prints. Relevant PPE such as a mask and gloves should be used when utilising this method. ### Summary | Category | Rating | | -------------- | --------- | | Speed | ★ ★ ★ ★ ☆ | | Finish Quality | ★ ★ ★ ★ ☆ | ![](https://1820679795-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LXautSvCbUco5Lv7YrH%2F-LjnRapsWsb5qvBE5SGY%2F-LjnRf_X1QLaolatXyzA%2FIMG_2934.JPG?alt=media\&token=ffb216eb-12df-4d1b-b4b3-031041d34e3f) ### Materials * High-cover aerosol paint + primer (such as Rustoleum 2X) * Acrylic or enamel fast-drying spray putty (such as Superfine High Build Filler) * Isopropyl wipes or similar to clean parts ![](https://1820679795-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LXautSvCbUco5Lv7YrH%2F-LjnRapsWsb5qvBE5SGY%2F-LjnT5ac5nkdzSNH7xSf%2FIMG_2764.JPG?alt=media\&token=840c4ff9-1b29-4eef-a26c-2e14d1550be5) ### Method 1. Ensure that your printed parts are clean and dry, **wipe the parts** down with Isopropyl wipes or a similar product and let dry.\ 2. Begin by applying a **thin coat** of high-cover spray-putty to the parts. Note that the spray-putty may cause blotching to your surface if applied too thick or unevenly across your surface.\ 3. Wait **30-45 minutes** (or as instructed on bottle) between coats. 4. Re-coat your parts a total of **3-5 times**.\ 5. Once you have applied all the necessary coats (according to how smooth you would like the finish of your surface) leave your parts to **dry overnight**. The spray-putty will fill up the gaps between the prints' layers and level your surface smoothly. 6. Apply a **medium coat** of high-cover spray paint to your part.\ 7. **Wait 10 minutes** between applying your paint coats. 8. Repeat the painting process **3-5 times** as necessary.\ 9. Wipe your parts clean and you are ready to go. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
